The cannabis industry is not as green as you might think.
Growing marijuana indoors is energy intensive, as it requires various equipment to regulate light, temperature, and moisture levels. Growers account for approximately 1 percent of electricity use in the United States, according to a 2012 study, releasing as much carbon dioxide as three million cars on average. And as more states legalize marijuana, grow houses could put a greater strain on public utilities. For the industry to grow sustainably, more energy efficient systems will need to be developed and adopted—and, as it turns out, there are plenty of points in the growing process ripe for innovation.
In a new study, researchers at the University of California–Davis’ Western Cooling Efficiency Center tested out a new dehumidification system for indoor farms, and found that it was much more energy efficient than traditional dehumidifiers.
